Application filed May 27, 1908. Serial No. 435,203.

T 0 all whom it may concern:

Be it known that 1, J ULIUS 'lINZ, a c1t1- at Detroit in the countv of lv a ne and State useful Improvements in Oil Burners, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to liquid fuel burners and especiall to oilburners of the wickless type.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

In the drawings, Figure 1 is a plan view of a burner embodying featuresof the invention. Fig. 2 is a view in section on or about line ."c-a: ofFig. 1.

Referring to the drawings, 1 indicates a hollow metallic casing of anypreferred symmetrical form, and having a central aperture 2 ofconsiderable size in its top 3. A substantially horizontal fuel supplypipe 4 leading from any convenient source of supply passes through theside wall 5 of the casing and has a suitable supporting fitting 6thereon, its inner end being branched and acting as support for a burnercup 7. The latter is centrally disposed in the aperture with its upperrim flush with the casing top 3 and is proportioned so that there issufficient space around it for air from the casing to pass therethrough.The cup is divided into a plurality of substantially circularcompartments each provided with central or axial upright nipple 8extending from the top of the compartment through its base andscrewthreaded into or otherwise properly secured to one of the branchesof the fuel pipe i. The space between each nipple and the wall of itscom artment is packed either with a mixture 0' shredded asbestos andfire clay 9 or like suitable refractory material which will readilyabsorb liquid. A crown 10 with radial ducts 0r passages 11 in its upperface is secured in the upper end of each nipple so that oil passing upthrough the nipple flows over onto the surrounding mass 9 which becomessoaked thereby. lhe compartments are connected with each other bygrooves 12 in the upper edge of the division walls.

A plurality of symmetrically disposed slides 13 of any preferred formare secured in the wall 5 of the casing; a central aperture ofconsiderable size is formed in the casing base i scre' -t of Michigan,have invented certain new and pregnated.

14- Which is controlled by a damper 15 of fsuitable construction;preferably this is a zen of the ljllltSCl States of America, residingcircular disk having an axial spindle l6 hreaded through the centralboss 17 in sp er 13 of appropriate design secured across the baseaperture.

The operation of the burner which is especially adapted for potterykilns, brick furnaces, and the like, is as follows:The fuel oil ispoured through the supply pipe so that it overflows through the ducts ofthe nipple crown into the surrounding mass of clay until the latterbecomes thoroughly im- The oil is then ignited and a sufficient amountallowed to flow through the fuel pipe thereafter to keep the flame atconstant height. Air is admitted through the central damper and theflame is directed obliquely upward from the burner by propermanipulation of the slide in the side of the casing as the opening of aslide at one side of the case deflects the flame obliquely in theopposite direction. By this arrangement a smokeless flame is obtainedand as the metal of the burner is shielded by the clay and asbestos,save at the rim, the flame does not carry away any salts or oxide fromthe metal to be deposited on and disfigure articles in the kiln in whichthe burner may be used. The burner is practically indestructible andsimple and readily constructed.

Obviously changes in the details of construction may be made withoutdeparting from the spirit of the invention, and 1 do not care to limitmyself to any particular form or arrangement of parts.

-What I claim as my invention is 1. A liquid fuel burner comprising acasing having an air outlet in its top air inlets in the casing sidesand base, a cup in the outlet having a plurality of compartmentstherein, a bed of refractory absorbent material filling eachcompartment, a central upright supply nipple extending from the base ofeach compartment to the surface of the bed, a crown on each nipplehaving radial distributing passages in its upper end adapted to directliquid from the nipple evenly over the surface of the bed, a fuel supplypipe connected to the nipples, an adjustably secured damper governingthe air inlet in the casing base, and a plurality of adjustable slideclosures governing the air inlets in the casing side.

2. A liquid fuel burner comprising a casing having an air outlet in itstop, an air inlet in its base, and air openings in its sides, a fuelsupply pipe through the casing side, a cup i in its upper face adaptedto distribute liquid supported on the pipe centrally in the outletevenly over the bed, a damper governing in and provided with a pluralityof compartl the base inlet opening, and slide closures ments connectedby channels in the upper t governing the side openings of the casing.

5 edges of the division Walls, a bed of refractory absorbent materialfilling each compartment, in presence of two Witnesses.
